DETAILED DESCRIPTION OF THE INVENTION

Design #1:

This type of Underground Irrigation System consists of spiral pipes that can be made of ¾″, or ½″, or other diameter steel spirals and covered with FWDM.

Because of outside pressure, it is necessary to provide the spiral inside the pipes, to form and keep the round shape for FWDM.

FWDM needs to be strong and tight enough to withstand outside and inside pressure and keep water from splashing from FWDM surface, and at the same time it should allow water to penetrate FWDM and soak the environmental substance. Thickness of FWDM can be ⅛″ or different to comply with the design. FWDM will be provided at the factory and unit should come ready to install.

During the landscaping, the system needs to be assembled within the borders of lawn by connecting spiral pipes to 1″, or ¾″, or other size Poly Vinyl Chloride (PVC) pipe, with 6″ space or larger between connections, using clamps. Sleeves that are not used should be closed with caps.

After system is assembled and connected to the main feeding water pipe, it needs to be tested. Topsoil needs to be placed above the system to provide smooth surface and sod should be placed above the topsoil following that procedure.

During the watering, water under the pressure goes through the spiral pipes and soaks FWDM that soaks the surrounding topsoil from which the grass roots take moisture. In the future, if the system needs to be extended, caps can be removed and new spiral pipes connected to the existing pipes, or to the additional 1″, or ¾″, or other size PVC pipe with sleeves. If it is necessary to shrink the existing system, it can be done easily by cutting and capping the pipes.

Design #2:

This type of Underground Irrigation System consists of pipes that can be made of ¾″, or ½″, or other size in diameter WDM.

Drench pipes that are made from WDM need to be strong and thick enough to withstand outside and inside pressure and keep water from splashing from WDM surface, and at the same time it should allow water to penetrate WDM and soak the environmental substance.

During the landscaping, the system needs to be assembled within the borders of lawn by connecting drench pipes to 1″, or ¾″, or other size PVC pipe, with 6″ space or larger between connections, using clamps. Sleeves that are not used should be closed with caps. After the system is assembled and connected to the main feeding water pipe, it needs to be tested. Topsoil needs to be placed above the system to provide smooth surface and sod should be placed above the topsoil following that procedure.

During the watering, water under the pressure goes through the drench pipes and soaks the pipes that soak the surrounding topsoil from which the grass roots take moisture. In the future, if system needs to be extended, caps can be removed and new drench pipes connected to the existing pipes or to the additional 1″, or ¾″, or other size PVC pipe with sleeves. If it is necessary to shrink the existing system, it can be done easily by cutting and capping the pipes.

Design #3:

This type of Underground Irrigation System consists of 3′×3′ or other size units that can be made of ¾″, or ½″, or other size pipes, which cast or welded in 6″×6″ or other size cells. Unit can be made of PVC or other materials, with small holes around the pipes and covered with FWDM to prevent the clogging of the holes with dirt and roots.

Size of holes is approximately {fraction (1/32)}″ and can vary, as well as a quantity of them per square inch of pipe's surface, depending on how tight and thick FWDM will be around the pipes, and pressure of water in the system.

FWDM needs to be strong and tight enough to keep water from splashing from FWDM surface, and at the same time it should allow water to penetrate FWDM and soak the environmental substance. Thickness of FWDM can be ⅛″ or different, to comply with the design. Holes and FWDM will be provided at the factory and unit should come ready to install.

During the landscaping, the system needs to be assembled within the borders of lawn by connecting 3′×3′ units to each other using clamps. Sleeves that are not used should be closed with caps.

After the system is assembled and connected to the main feeding water pipe, it needs to be tested. Topsoil needs to be placed above the system to provide smooth surface and sod should be placed above the topsoil following that procedure.

During the watering, water under the pressure goes through the holes and soaks FWDM that soaks the surrounding topsoil from which the grass roots take moisture. In the future, if system needs to be extended, caps can be removed and new units connected to the existing units. If it is necessary to shrink the existing system, it can be done easily by cutting and capping the pipes.

General note for Design #1, Design #2 & Design #3:

With the time, grass roots grow around the pipes and it will increase the watering time, which needs to be adjusted.

Advantage of the Invention:

These systems (Design #1, Design #2 & Design #3) will consume much less water than the perfectly adjusted traditional sprinkler systems, because it delivers moisture right to the roots of grass or plantations and water does not evaporate from the surface of the lawn, especially during the hot weather days.

It also, does not spray outside the lawn, and it is a known fact that approximately 10% to 30% of water sprayed beyond the lawn, waters the dry ways or flows into the drainage system.

If water is diluted with a fertilizer, people will not be exposed to the dangerous chemicals. Regularly, when sprinkler system sprays that kind of solution, especially when the wind blows, water particles drop on people's skin or on the surfaces that people touch.

It is not necessary to leave the lawn or take another route for a walk during the watering time.

People do not need to wait until surface of the lawn will dry up to play or use for the social activities, or to cut the grass.

Non-potable water can be used and it will not cause any odor or disinfections problems for the property owners. This option will contribute additional savings to the water consumption for the local utility companies.

It allows to irrigate the lawn even in the afternoon hot sunny hours, when the traditional system can “burn” the grass. Those hours are the most productive in the sense of grass grow, because photosynthesis level is rapidly increasing and moisture is essential during this process. Because of that, the appearance of lawns with the above described systems will be much more attractive than the lawns irrigated with the traditional sprinkler systems.

Traditional sprinkler system's electrical valve and control panel for On or Off mode and water flow scheduling can be used.

These systems, once installed, do not need to be adjusted and repaired every season, and can work with the exiting systems as well.

Conclusion:

These systems are very convenient and efficient, especially for the small lawns.

Today, when the rapidly increasing water consumption becomes the huge problem for the society, these systems can save tremendous amount of water (money) and will improve the ecological situation.
